VMware has also 'fessed up to a problem that affects VMs running in Workstation that have virtual printing turned on. This flaw means “a Windows-based Virtual Machine to trigger a heap-based buffer overflow [and] may lead to arbitrary code execution in VMware Workstation running on Windows.”

Mac admins: stop being so smug. VMware has a problem for you too, as “The graphic acceleration functions used in VMware Tools for OS X handle memory incorrectly.”

“Two resulting NULL pointer dereference vulnerabilities may allow for local privilege escalation on Virtual Machines that run OS X.”

This last bug also needs a little attention beyond the desktop from ESXi users, because there's a patch for it that also fixes the OS X problem.
